Concrete repair is our area of expertise and what we seek to do is supply you with a long-term solution to your individual issues. Everything has its weaknesses, even a tough material like concrete, but that doesn’t mean that there aren’t ways to help. With our joint sealing and waterproofing service we apply the appropriate measures to assist in safeguarding structures against the detrimental effects of water.
One of the most crucial things you need to understand about filling or sealing concrete joints is that they aren’t the same. In fact they possess vastly different purposes. A sealer for instance is soft, and can the contraction and expansion of concrete slabs. The function of a sealer is to halt the advances of dirt, ice and water into the joint and subgrade. Sealers also have some aesthetic value.
A filler is a more rigid substance that supports the joint’s edge as heavy traffic crosses. This variety of material is only useful with saw-cut joints, as rounded tooled edges are unable to support the filler. Both fillers and sealers should be installed only after the slab has had the opportunity to shrink as much as possible. Fillers in particular are only productive once the concrete has gone through the majority of its shrinkage.
Effective sealants have to bond to the concrete, possess the ability to handle contraction and expansion, and must be impermeable. Before a sealant is installed, the joint has to be dry, as well as being vermin and dust free.
At Churchill Concrete Technology we highly recommend our sealing and waterproofing service for every ground level and basement concrete structure. Every situation is unique however, so before we apply our safety measures, we will take a thorough look at the structure to determine the best course of action.
