Expansion joints are placed in floors to allow for shrinkage as concrete cracks as it cures. The joints are often trawled into the floor or occasionally cut after the floor is hard enough to walk on. During the curing phase of the floor these joints often develop cracks that go to the bottom of the sand or gravel base below. If you try to fill these cracks with a liquid it often leaks out the bottom leaving the joint open again before the product is set up.

In some cases it is best to leave expansion joints. Temperature changes force concrete to expand and contract. Joints cut in sidewalks are designed to allow for expansion and contraction without cracking. For most interior applications expansion and contraction is not very severe. The covered areas allow for slower temperature changes and most interior spaces are climate controlled to some degree. Food processors and other operations that have health concerns usually fill expansion joints to avoid associated cleanliness issues regarding mold, mildew and insect problems that the joints can promote.

Durall has developed an expansion joint grout that can quickly fill these joints to level without the danger of it leaking from the bottom. In addition, the grout is extremely hard, cures rapidly and has excellent adhesion properties when applied to cleaned and prepped floor joints.

First, clean your floor with a high alkaline cleaner to raise the pH level to around 12 using an aggressive scrubbing brush with a rotary scrubber. Follow the alkaline cleaner with an acidic cleaner pulling the pH down to 4 and scrub rinse once or twice with water being sure to clean the joints as you go. Often using the pressure from a water hose during each phase will blast dirt out of your joints. Next, mix up Durall's grout with gloves and take a hand full and scrub into the joints at a 45-degree angle. Use a putty knife to remove excess material and smooth the top of the grout even with your floor. Allow at least two hours to cure. After the grout hardens it is often helpful to scrub your joints again with fresh water to remove any residue left from your scrubbing process. You will still see the joints but they will be smooth, hard and level. With a coat of epoxy or urethane the newly coated surface will look great with a minimum of wearing. Durall Industrial Flooring supplies kits of materials that are customized to owner specification and delivered directly to the job site.

Most concrete substrate can be resurfaced, even decorative concrete such as slate impression, faux brick and even old style cobble concrete. The first thing we must access is how solid the existing concrete is and how bad the cracks are, most cracks can be filled with a flexible type filler or a floor level product like Dribond Floor Level Tuff or Standard © ™ and even where concrete has delaminated off fascia work there is a great product called Patch & Anchor © ™ also by Dribond.

If you have slate impression or faux brick style concrete we can simply grind the surface back to level and then add colour and style Spray Paving the area in a myriad of patterns and colours. The cost saving from cutting and pulling the old concrete and disposal costs is huge not to mention less hassle no bob cats, trucks, broken drain pipes and then if it rains half way through the digging out you can be stuck without a driveway for weeks.

For old style cobble pressed concrete in most cases we fill up the existing pattern with a floor level product and then applying a final coat using a hand trowel to achieve the final level. Once this is done we normally leave this to dry for up to 48 hours then apply the spray pave process to add design and colour.

Spray pave is not a paint or "epoxy" type of finish. Spray pave is a cement and polymer based product which also adds style and texture and has an amazing non-slip qualities un-matched by any other concrete resurfacing products and should last as long as the concrete it is applied to as long as it has been correctly applied and maintained.

By applying spray pave you can open up areas, splash colour in those old dull spots, transform your existing driveway from drab and dull into a masterpiece of colour and style, the only limit is your imagination as the possibilities are endless.

So if you are contemplating "ripping the boring old grey stuff out" think of the $$$ you could be saving by resurfacing and then spray paving.

The era of tarmac driveways has diminished considerably with the introduction of the imprinted concrete driveways which is stronger and long lasting then less durable tarmac due to its make and feature set.

The most prominent part of any house is its driveway which gives first impression to any visitor. Therefore, it becomes very important to build your home without compromising on the quality of material used for its interiors or exteriors including the driveways.

When you are selecting driveways, you have the right to know and learn about new options available today which are more resilient and affordable. Therefore, with all said and done, you have two options that would be the best possible fit in terms of quality and price, an imprint concrete and tarmac driveways.

Every home owner looks forward to get the best for their home. Some of them succeed in getting what they wanted and some of them are left dissatisfied. Most often many of these home owners are not very satisfied about the service of tarmac driveways because it's not easy to remove car engine oil stains, the surface cracks due to heat conditions and also tends to lose its surface grip over 1-2 years.

If you intend to select the best amongst the two then by far go for the concrete driveway path in comparison to tarmac driveways. The word 'concrete' itself signifies strength, durability for any terms it's used for. Imprint concrete also measures cost effectiveness as well when talking about walkways, patios, driveways, floors etc.

A concrete driveway allows its use in a much wider mix and variety of climates in comparison to tarmac. Concrete surface will be stronger and harder, which can bear any climatic conditions irrespective of whether it's cold or warm. You can still soften the hard matter using runners or rungs which will also protect the object from breaking or shattering at the same time protects small children from getting hurt, who are more prone to crawling or falling on concrete surface.

Tarmac is no longer a professional choice for the reason that it cannot be tailored like concrete driveways. With the imprinted driveways you can add many effects like the slate, granite, flags, block pavers, cobbles etc, improving on the overall looks of the entire home adding great value.

Major advantages of Imprint Concrete driveways:

Adds additional value to your home
It has very low overall maintenance
Its oil & stain resistance thus can be kept clean all the time from the leaking oil of your car.
It does not losses its color and has permanent texture
You will not find any slip surface as once fixed it remains forever
Available in extensive choice of various colors and pattern


In other words, your home is now the most valuable and talked out thing around you, which keeps gaining the value momentum day by day. Feel your home with imprint concrete driveway, which looks good and stay good all the time.
