It’s a Hebel Monday here at the office,

So what is Hebel? I can hear you say.

Hebel is a versatile building system. It comes in blocks or panels, and is made from Autoclaved Aerated Concrete.  (AAC) It contains steel reinforcements and is available in a variety of sizes.

So what, you say? Isn’t that the same as using bricks? … Well apparently NO. There are many reasons why Hebel is a well loved alternative, when you are looking to build a new home, or renovate, you are bombarded with selections, and are asked to make literally thousands of choices and sometimes on products you know very little about. Keeping this in mind I thought I would go on a little survey, as a representative for the civilians of the non construction world to gain a better insight into what all the hoo-ha is all about. So I brought out my journalists note pad, pen, and serious questioning voice, and went around the construction department and asked each of the boys why they loved Hebel.

Danny: It aces every other product on the market for thermal properties. It provides the best thermal and acoustic protection. Where bricks retain heat, the technology that has gone into the Autoclaved Aerated Concrete system has resulted in a product that really reduces the reliance on heaters and air conditioners. I have used Hebel in my own home, and when you are located in a busy high traffic environment you really notice the difference with the significant sound transmission and absorption not only from out side to inside, but also between walls and levels of the house. Because it is also so lightweight I did not have to compromise on a uniquely contemporary design process as it reduced the need for excessive piering… It also allowed for a cleaner construction site! No bricks everywhere!

Chris: Hebel is awesome because it is so fast to install. It is up and finished in days instead of weeks, which then means your scaffold can be dropped faster, in turn decreasing costs. It drops building overhead and timeframes with the removal of many trades. I have read that installing one Hebel panel is the same as laying 75 bricks! Beside this it’s an environmentally a cleaner choice, so its win win.

Will: Hebel works so well because it is a quick traditional wall system. It‘s low maintenance and is very quick to install. It doesn’t crack like bricks, and provides more advantages in terms of thermal insulation and fire properties to cladding, which brings it in as a top contender for an external façade system. It looks great. Its sleek, and awesome, modern, and versatile… Really, it’s just like me!

so there you are Hebel: In a nut shell: Its strong, pretty, can be coated with almost anything, provides a sound barrier, helps your wallet stay fat,  best of all it was developed  in Scandinavia, and lets face it what doesn’t Scandinavia do well!

If you are a home owner looking to renovate, or add extensions, or are you looking to build a new home, or development? Hebel is the answer to your flooring, internal walls and external facade cladding . Thank you CSR.

building repairs helifix bars

How fast is this year progressing?! We have had a number of quotes for repairs on cracks occurring in brick walls, render and masonry over the last few months. In this light the team at Contractors United thought we would put together a little information on how we use Helifix products to structurally repair cracks and return your property to its former glory! Below you will find the common causes of cracks in bricks and render, and how Helifix bars and helibond grout work to fix these problems.  Rest assured our skilled and experienced workforce can manage all cracks large or small, if you have found crack damage on your property don’t delay, contact us for a quote today!

The two most common causes of cracks in brickwork and other masonry are usually, foundation movement and thermal movement and moisture uptake or loss

Foundation movement: Cracks occur when forces either externally, internally within a building, or as a result of chemical changes within the building’s materials are greater than it can withstand. Cracking and movement can be structurally dangerous. Differential movement throughout a building may be a consequence of poor design, ageing or changing environmental conditions to which a rigid building cannot adapt without fracturing.

The form and positioning of cracking depends upon the building’s weak points, particularly around doors and windows and where floor and roof connect to walls, such cracks are normally widest at the top. Other factors are the size, shape, and position of the crack, the age of the crack indicating repetitive movement, and crack widening suggesting settlement or support failure.

Thermal Movement and moisture uptake or loss:  Clay bricks take up moisture and grow whereas silica and concrete bricks lose moisture and shrink over time.  The mortar between the joints is also shrinking which results in different vertical and horizontal movements. Where cracking from thermal movement and moisture variation does occur it is normally vertical and often worst at the building corners.  This type of cracking is more common in residential apartments and commercial buildings.

Using a professional to correctly diagnose the cause and effect of the problem is the key to carrying out appropriate systems to rectifying your structure. There are many Helifix products that can be used in various situations to resolve issues with cracked bricks and render. Helifix repair and reinforcement products have a concealed and non disruptive installation technique, they ensure the long term strengthening of all masonry structures. Some of the basic uses of Helifix bar and grout are to cracks in brick walls, cracks in rendered walls, Cracks in block walls, and cracks near corners.

The application we use are extremely versatile and provide a reliable and cost effective solution to basically all commonly occurring structural faults an the results rendered leave your property visually unaltered and fully stabalised. The Helifix bars are made from stainless steel, are non shrink and redistribute the tensile loads along the masonry whist still facilitating flexibility to accommodate for natural building movement.

Now that you are all experts on cracks and helifix, here is the bottom line. Cracking and movement can be structurally dangerous. Whether it be a consequence of poor design, ageing or changing environmental conditions it is something that needs professional assessment and rectification.
