Concrete decks are exposed to the elements year-round; constant moisture exposure can lead to cracks and deterioration. By waterproofing your deck, you create a protective barrier that will help to prevent these issues, ensuring the long-term durability of your deck.

Enhanced appearance

Who doesn’t want a deck that looks stunning all year round and long into the future? Waterproofing not only protects your deck but also enhances its overall appearance. It can give your deck a fresh, clean look, making it more inviting and enjoyable for family gatherings or outdoor parties.

Increased lifespan

Let’s face it: As we mentioned earlier, decks aren’t cheap to build or replace. Waterproofing your concrete deck can significantly extend its lifespan, saving you time and money in the long run. With proper maintenance and regular inspections, a well-protected deck can last many years.

Easy DIY pothole repair – goodbye bumpy concrete!

July 12, 2023 by The Cohe Team

Have you ever driven down a road or walked on a path only to be jolted by a sudden dip in the concrete? Potholes are a common issue that can wreak havoc on driveways, paths and roads. Not only do they create an unpleasant and bumpy ride, but they can also lead to extensive vehicle damage and potential accidents.

However, there’s good news – with the help of our innovative products, DIY pothole repair has simply never been easier. With this article, say goodbye to bumpy concrete as we offer you expert tips for achieving a long-lasting fix.

How to identify a pothole quick-smart!

Accurately identifying potholes is the first step towards a successful repair. Look out for tell-tale signs such as cracks, depressions and loose gravel around any damaged area on your property. These signs are a typical indicator of weakened concrete that needs your immediate attention. By identifying potholes early on, you can prevent them from growing larger and causing more extensive long-term damage and requiring costly professional repair.

It’s not just about aesthetics, though. By promptly addressing potholes, you can prevent damage to your vehicles and reduce the risk of any accidents. Whether you have a busy driveway or live right on a public road, it’s essential to take action and fix those potholes before they become more troublesome.

What sort of tools do you need for DIY pothole repair?

To tackle DIY pothole repair effectively, you are always going to need the right tools and materials.

PAR is specifically designed to permanently repair asphalt in all weather conditions; no primers are required. It has been proven to last longer than existing pavement and is capable of supporting traffic immediately following installation.

PAR can also repair holes in concrete, but we recommend MG-KRETE as being the best to use if you are looking for something to repair issues with concrete.

In addition to this, you will need basic tools like a shovel and tamper, as well as safety equipment such as gloves and eye protection. Before starting the repair, always ensure you have the necessary safety measures in place to protect yourself.

The step-by-step DIY pothole repair process

DIY pothole repair using our products is simple and hassle-free. Here’s a guide that will help you achieve a smooth and long-lasting repair:

Prepare the damaged area by removing loose debris and cleaning the pothole thoroughly.
Apply our pothole repair solution (PAR) according to the instructions. PAR is a high-performance, cold-mix asphalt that can be easily applied with no special equipment required.
Compact the PAR by tamping it down using a tamper or the back of a shovel.
Ensure the edges of the repaired area are properly sealed to prevent water infiltration and deterioration.
Allow the repaired area to cure for the recommended time, ensuring it is fully hardened before subjecting it to heavy traffic.

What are our top tips for a long-lasting repair?

To ensure a durable fix, it’s essential to properly compact the PAR during the repair process to achieve optimal density and stability. Make sure you seal the edges of the repaired area properly and regularly inspect the area to address any signs of wear and tear promptly.

What are the benefits of DIY pothole repair?

By tackling the problem quickly, you can save significant costs instead and prevent it from becoming worse and requiring the help of professionals. By taking matters into your own hands, you can save on labour costs while achieving professional-looking results.

Best product to fix cracks in a concrete driveway – MG-Krete

April 27, 2023 by The Cohe Team

Winter weather can be tough on roads, paths and driveways, especially when they’re made of concrete.

Freeze/thaw cycles, heavy loads and persistent rains can all cause cracks to form in the surface of a concrete driveway, and if left untreated, these cracks can become larger, leading to even further damage.

With winter weather just around the corner, now is the time to take action – before it’s too late!

Why winter is the worst for concrete

Concrete’s biggest enemy is water and for many reasons. Winter is when it rains the most, so more rain means more water, which means more problems.

Concrete isn’t 100% waterproof, so rainwater will always seep into your driveway, no matter how recently you poured it. In winter, that water tends to freeze, and when water freezes, it expands, pushing everything around it. This freeze/thaw cycle is the most common reason for cracks in a concrete driveway.

Other culprits include soil settling and abiding rainfall, both of which are really just the same problem; water under your driveway. If the soil starts moving because it’s saturated, then the concrete on top will crack with the strain, just like a miniature earthquake.

On top of mother nature’s attack on your property, heavy loads such as cars and trucks can also cause cracks to form. If you own a larger vehicle, like a flatbed or a van, then you can expect more pressure and, therefore, more damage.

Fortunately, there is a solution that can help you fix those cracks before it’s too late: MG-Krete.

The ultimate concrete repair solution

MG-Krete is a specially-formulated product that is designed to repair cracks in concrete surfaces. Whether your concrete driveway has small surface-level cracks or more extensive damage, MG-Krete can help you restore it to a like-new condition.

It lasts much longer than traditional cement-based patch material and cures rapidly, so you can drive over it within 45 minutes! It withstands heavy traffic, doesn’t shrink, requires no long-term maintenance, and creates a surface that is more resistant to moisture, salt, gas and oils.

How to use MG-Krete to fix cracks in a concrete driveway

Here’s how to repair cracks in your driveway before winter weather arrives.

Step one: Assess the damage

The first step in repairing cracks in your driveway is to assess the severity of the damage. If the cracks are small and only surface-level, MG-Krete can be used to fill them in and create a seamless repair. However, if the cracks are more extensive or if there are multiple cracks in close proximity, a more comprehensive repair may be necessary.

Step two: Clean the area

Before applying MG-Krete, it’s important to clean the area around the crack to ensure a strong bond with the surrounding concrete. Use a wire brush or pressure washer to remove any dirt, debris or loose concrete.

Step three: Mix and apply the product

Follow the instructions on the packaging to mix the MG-Krete solution. For small cracks, you may only need a small amount of the product, while larger repairs may require more. Using a trowel or putty knife, apply the mixed MG-Krete to the crack or hole in your driveway. Work the product into the crack and smooth the surface to create a seamless repair. Make sure to apply the product evenly and avoid overfilling – you don’t want a speed bump in your driveway!

Step five: Allow to Dry

Allow the MG-Krete solution to dry for at least 45 minutes before using the driveway. During this time, make sure the area is protected from water, snow, and other weather conditions.

Fix cracks in your concrete driveway with our help!

MG-Krete is ideal not just for concrete driveways but also for an unlimited range of other repairs, including:

Roadways
Potholes
Footpaths
Industrial Floors
Parking Decks
Trip Hazards
Access Ramps
Steps & Stairs

We have the easiest concrete waterproofing products for you to use!

August 8, 2022 by The Cohe Team

Do you have a DIY concrete project that needs doing but you don’t know what concrete waterproofing products to use?

With spring approaching, now is a great time to get all your jobs done. However, deciding on the best concrete waterproofing product is important in ensuring the job is done right.

Water is one of the most detrimental causes of structural damage such as cracks, frost damage, algae growth, and salt corrosion. Once the concrete erodes and deteriorates, it can be very expensive to repair.

Therefore, a waterproofing concrete sealant needs to be applied to protect it.

Here, we’ll tell you the concrete waterproofing products that are the easiest to use and more importantly, will get the job done right.

How our concrete waterproofing products will help you

A concrete waterproofing sealer prevents cracks from forming; the more cracks that appear, the more water can get in.

The wear and tear of concrete will slowly show over time. But if the surface of the concrete starts to deteriorate, the inside structure may be as well.

This deterioration is what you want to avoid. Not only can this turn into a big job to fix, but a timely and costly one too.

Prevention is crucial, and using a waterproof sealant provides the answer.

Our concrete waterproofing products will help you:

Reduce excessive mould and mildew build-up
Water resistance and dampness prevention
Strengthened structure – less moisture, fewer cracks, and less vulnerability to all weather elements
Increased property value – having waterproofed concrete in all the areas of your home or business gives potential buyers the confidence there won’t be any costly maintenance issues
A rich and glossy appearance that looks clean and professional
A finish that helps resist acid, oil, grease, and general stains

What is the best product for waterproofing concrete?

The best concrete waterproofing products that are quick and easy to use are our range of Cohe products. This includes our popular Liquid Rubber Waterproof Sealant.

Why?

Our range of products is quick and easy to use, but they are also environmentally friendly, non-toxic, cost-effective, and of the highest quality.

If you are unsure, please contact us to discuss your requirements.

Waterproofing materials for concrete – what you’ll need

Before applying the Liquid Rubber products recommended below; ensure your surface is clean and dry.

It must be free from dust, dirt, oils, varnishes, surface flaking, poorly bonded or glossy paint, sealers, salts, or any other substance, which will create a barrier and disrupt Liquid Rubber from adhering properly.

Liquid Rubber can then be applied like paint using a brush, roller, or spray gun.

Liquid Rubber Seam Tape

How do you fix concrete yourself? With our DIY concrete repair that works!

March 13, 2022 by The Cohe Team

Cracks in concrete not only make your driveway, patio, or steps look undervalued, they can also lead to further problems as moisture seeps into the concrete. Prevention and maintenance is always your best protection against further costly and unnecessary problems. If you’re looking at fixing your damaged concrete yourself, using our DIY concrete repair will help you get the job done the easy way.

Whether you’re fixing a crack in your driveway, a concrete floor or a pothole, we can guide you in the right direction so you can fix it yourself with confidence.

The different causes of damaged concrete

Before you repair anything, it’s best to know what caused the problem in the first place so you not only have a better understanding but have a better chance of success with a DIY concrete repair that lasts longer.

Corrosion

Concrete corrosion is the chemical, colloidal deterioration or disintegration of solid concrete components and structures due to attack by reactive liquids and gases.

Corrosion is one of the biggest causes of concrete deterioration, so reinforced concrete must be installed and maintained correctly to minimize the risk of damage.

Temperature variations in concrete

Changes in the temperature of concrete can cause cracking. As the concrete gets hotter, it expands; as concrete gets cooler, it contracts. This is similar to many other materials you have probably learned about.

Plastic shrinkage

When the concrete is still in its plastic state before the hardening phase, it is full of water. This water takes up space and makes the slab a certain size. As the slab loses moisture while curing it gets a bit smaller.

Freeze-thaw cycle

If your concrete floor is located outdoors, it’s exposed to many elements. That means rain, wind, and the endless freeze-thaw cycle, to name just a few natural forces. Like corrosion, moisture is another primary culprit of concrete damage. When excess moisture in your concrete freezes, it expands, putting pressure on cavities within the material.

The concrete dries too quickly on application

If the concrete dries too quickly, it will lose moisture which can cause fine cracks throughout the concrete.

Improper installation

Improperly constructed joints, excessive moisture during curing or in the mix, and premature sealing are just a few potential examples of an installation gone wrong. Signs the job was rushed is finding crazing, spalling, and blisters.

How to tell your concrete needs repairing

Cracks appearing in the concrete

The most obvious sign that your concrete may need repair work is the appearance of cracks. Cracks in concrete can be caused by the soil underneath expanding and contracting due to weather conditions. If you have noticed cracks in your concrete, repair them promptly or seek professional advice.

Signs of concrete ageing

Like everything, expect concrete to age over time. A combination of cracks, pooling water, potholes, and unevenness are all signs of damage caused by ageing. The concrete will have noticeable signs of ageing and will look worn out.

An uneven appearance

Another sign that concrete repair is necessary – if your concrete floors, external areas, or walls seem uneven. If you fail to take action when you notice your concrete areas are no longer even, you could end up with a serious issue. This includes crumbling and breaking, which causes instability and could also lead to injury.

Potholes

Like cracks, potholes are caused when the ground underneath it expands and contracts, as well as by the constant pressure from your vehicles. A pothole is more hazardous than a crack, as the hole can cause serious damage to not only cars but to people who use the driveway.
