Everest Systems recently launched ECO-LEVEL, a fast cure and extremely durable self-leveling repair compound for the elimination of ponding areas on aged flat roofs.

OMG Roofing Products, a division of OMG, Inc. and leader in commercial roofing accessories and productivity tools, has announced the new OMG ReadySump RetroDrain as an innovative extension to the OlyFlow lineup of retrofit roof drains.

The removal of water from the roof surface is critical to the success of the system and warranty compliance.

 Understanding the “Leak Triangle” and utilizing the 3-D approach—deflect, drain and dry—will enable the design/construction team to be more effective in analyzing problems and recommending solutions.  

A drain shall be placed around the perimeter of a foundation that consists of gravel or crushed stone containing not more than 10-percent that passes through a No. 4 (4.75 mm) sieve.
