Testing & Elevation Surveys
The first step in any successful floor covering project is to know where you are to begin with. Two key items need to be known before any floor covering is considered.
- What is the moisture level in the concrete slab
- What are the existing elevations and elevation changes of the slab.
We offer services to help with both. We offer moisture testing per ASTM standards to determine the level of moisture in your slab. In addition we offer elevation surveys to determine where the existing floor elevations are. Both of these services are important because once you know where you are at, we can help you get to where you need to be.
Moisture Mitigation
Even after slabs have cured there can still be moisture vapor present within them. Most commercial floor covering needs RH readings of 85% or below to install and warrant the floor covering. The extreme fast pace construction schedules of today also causes flooring installations to be performed before full moisture is released from the new or existing concrete slab. When RH readings are not within specifications the solution is to install a moisture mitigation system.
The first step is to mechanically prepare the concrete floor slab to a CSP 3 per ICRI guidelines. Next step is to install a 2 part 100% RH moisture mitigation system including pre-treatment of cracks . This system can be applied after 7 days of slab cure thus expediting construction schedules. Many commercial floor glues require 1/8”-3/16” minimum concrete to bond to. In these cases the final step of the system is to prime the moisture mitigation with a non-porous primer and then install typical 3/16” nominal self-leveling underlayment. The requirement of depth of leveler is driven by the floor covering glue specification. At this time additional depth of leveler can also be installed to meet specific tolerances or height requirements.
All of our equipment is dustless attached to Hepa Filter vacuums and meets current OSHA silica standards.
Leveling
Many floors are not poured to the tight specifications of commercial floor covering. In many cases 1/8” in 10’ is the tolerance required to install floor covering. The solution is to install self-leveling cementitious underlayment. We can take any slab from existing condition to final desired tolerance. The first step is to mechanically prepare the slab to a CSP 3 per ICRI guidelines. A primer is then installed to the concrete. Pins are then set to desired height of final leveling. Self-leveling is then poured to meet the pins. All of our equipment is dustless attached to Hepa Filter vacuums and meets current OSHA silica standards.
