Frequently Asked Questions
Which primer do I use on concrete?
It depends on the substrate and the product that follows. The range stocks primers for concrete, damp substrates, and different membrane systems. Check the technical data for the primer and the product it goes under. Do not guess the match from the label alone.
How do I choose a waterproofing membrane?
Match the membrane to the substrate, the moisture level, the traffic, and the approved system. The range has cementitious, polyurethane, and epoxy options for different jobs. Read the product data for cure time, coverage, and the conditions it handles.
What do I use to seal a joint in a concrete slab?
Put backing rod in the joint first, then seal with a sealant matched to movement and exposure. The range has polyurethane, silicone, and foam sealants for different joints. Check the joint width, movement, and whether the joint is internal or external.
Can I get raised paving pedestals here?
Yes. The range stocks Buzon pedestals, joist holders, spacer tabs, and couplers for external raised paving. Match the pedestal to the paver weight, the finished height, and the substrate. Read the pedestal data for the load rating and adjustment range.
Do you stock grout for paving joints?
Yes. Flexible grout, rapid-set grout, and gel foam grout cover pedestrian and light vehicle paving joints. Pick by joint width, the paver type, and whether the area gets vehicle traffic. Check the grout data for joint width range and cure time.
What do I use to repair a cracked concrete slab?
It depends on the crack. Structural cracks need epoxy injection. Surface cracks need a repair mortar or fairing coat. Movement cracks need a flexible filler. Check the crack width, whether it is moving, and the load on the slab before you choose.
