Concrete Repair Compounds

Concrete repair compounds cover several different repair jobs, from smoothing shallow defects and rebuilding spalled concrete to stopping active leaks and filling structural voids. The products in this category include cementitious repair mortars, fairing compounds, hydraulic water plugs, rigid epoxy repair compounds and construction grouts, so selection should be based...

Frequently Asked Questions

Which compound repairs a spalled concrete column?
A thixotropic mortar such as Mapegrout T40 builds on vertical faces without slumping or formwork, formulated to match medium-strength concrete so the patch moves with the parent.
What stops water leaking through a crack right now?
Gripset C-Plug. It is a rapid-set waterproof plug that seals active leaks in minutes. Structural reinstatement follows once the flow is stopped. Match the product spec to the job conditions before you start.
How deep can I apply repair mortar in one pass?
Per the data sheet only. Penapatch HB50 allows high-build passes; fairing coats stay under about 5mm. Exceeding per-pass depth traps heat and the patch cracks.
When do I need epoxy instead of cementitious mortar?
Where the section carries structural load or needs chemical resistance: Ardex RA-88 two-part epoxy. Cementitious mortars suit general surface reinstatement. Match the product spec to the job conditions before you start.
Which grout re-seats machinery onto repaired concrete?
Non-shrink Penatech HS (high strength) or HES (early strength). Ordinary mortar shrinks from the plate and leaves the bearing loose. Match the product spec to the job conditions before you start.
