25 years on thousands of members in hundreds of buildings, with over 36 pages of reference projects.
The repairs are permanent and should last the life of the original wood. We do give a four year limited warranty which has never been refused by a lender on house sales. We do provide structural certification letters, if necessary.
Epoxy coatings, acrylics, and elastomerics. Epoxy coatings are used when a very tough, abrasion and chemical resistant surface is required. Examples would be warehouse floors and restaurants. Elastomerics are synthetic rubber coatings used mainly for deck coatings where protection from moisture intrusion is paramount. Elastomerics are also used for underground wall waterproofing. Acrylics are used for very economical colored surfaces and where a clear finish is needed.
We have to chip out the loose concrete and clean the exposed surfaces in the cavity, usually by power wire brushing and or a device called a needle gun. We need to clean any exposed rebar and treat with a rust neutralizing coating. We then apply an epoxy bonding agent. We then fill the void with a high strength patching cement , such as Thorite Rapid Vertical. The American Concrete Institute has found that when an epoxy bonding agent is used, and a good quality patching material, the repair will be as good as the original member.
