Waterproofing Planter Boxes

Moisture Control

External features such as air conditioning ledges, bay windows and planter boxes are increasingly being used in commercial and residential building projects. There are many environmental benefits when using planter boxes in both homes and hi-rise buildings, not to mention the enhancement to the building design. But if not installed properly, these features allow water seepage that can potentially damage the structural components. Special consideration needs to be taken when waterproofing planter boxes and other external features, and we have the expertise to implement proven solutions.

Water damages exterior applied finishes and surrounding areas unless it is controlled. Unless drainage is provided a host of problems will occur – footings, mortar, bricks and foliage are adversely affected by water damage. Correct waterproofing adds value to your investment. No damage. No risk.

Proven Systems

It is generally accepted that most planter boxes leak, this should not be the case. The correct choice of an appropriate membrane combined with correct application and adequate drainage solutions will ensure that this is rectified.

We use proven systems like Tremco’s TREMproof®250GC which is a high-build cold liquid applied membrane.  Due to TREMproof 250GC unique chemistry, it is the ideal single component waterproofing membrane for high-build applications in both horizontal and vertical applications. High-Build Systems are used in critical below-grade waterproofing applications where additional membrane thickness is required for the success of your project. TREMproof 250GC is high solids, VOC compliant, modified polyurethane waterproofing membrane that can be applied to green or damp concrete in both standard and high-build systems.

We also use Sika’s Sikalastic® RoofPro system which is a liquid applied membrane with a 25 year track record of waterproofing protection for roofs, plaza decks, balconies, planters and similar applications. The system cures to a highly durable, seamless, fully bonded, waterproof, elastomeric membrane. Sikalastic RoofPro Systems incorporate high performance aliphatic base and top coats as well as a unique, highly conformable fiberglass reinforcement and are available in 10, 15, 20 and 25 year warranty configurations.

These products adhere to any substrate, vertical or horizontal and can be used in many ways, on roofs, planter boxes, fountains, etc…
