Tired of being pushed around by water and moisture problems? 
Synergy has partnered with the industry’s leader in developing and producing quality concrete waterproofing products.

How does moisture enter into my building?
Moisture is found in some form or another on every building site. The difference between a satisfied owner and a “problem” project is how you deal with this moisture. By developing systems that are designed to act together to provide complete protection, we can help you design and build a structure that is protected.

Concrete Waterproofing Applications:

  • Bridges
  • Parking decks
  • Plaza decks
  • Structural slabs
  • Vehicular, utility and pedestrian tunnel projects
  • Hospitals
  • Schools
  • Office construction
  • Commercial projects

Our concrete waterproofing products:

HYDRALASTIC 836 is a cold-applied, solvent-free, single-component waterproofing compound. It does not shrink, has a low volatile organic compound (VOC) content, and has a very low odor. It will not crack in extreme cold or slump due to softening at high temperatures.

MEL-DEK is a roll-type waterproofing membrane composed of a nominally 53 mil thick layer of polymeric waterproofing membrane on a shrink-resistant, heavy-duty, 12 mil thick polypropylene woven carrier fabric.

MEL-ROL® LM is a single-component, polymer-modified, cold-applied, water-based, liquid waterproofing membrane ideal for below-grade horizontal and vertical seamless waterproofing applications. We have taken the same high quality rubber polymers found in MEADOWS’ successful MEL-ROL “peel and stick” membrane, and converted them into a heavy bodied, high solids, quick drying liquid membrane.

MEL-ROL LM (ALL SEASON) can be used on new and remedial waterproofing applications on concrete or masonry block substrates. Application can be performed in colder weather when water-based products cannot be used.

MEL-ROL waterproofing system is a flexible, versatile, dependable, roll-type waterproofing membrane. It is composed of a nominally 56 mil thick layer of polymeric waterproofing membrane on a heavy-duty, 4 mil thick, cross-laminated polyethylene carrier film.

PRECON is used as a blindside mebrane in vertical applications where access to the positive side is limited. The membrane can also be used for horizontal applications for underslab waterproofing and vaporproofing.

MEL-PRIME™ is a ready-to-use primer available in solvent-based and water-based versions.

PROTECTION COURSE is a multi-ply, semi-rigid core composed of a mineral-fortified asphalt core formed between two outside layers of asphalt-impregnated reinforced mats.

PERMINATOR® underslab vapor barrier can also be used as a protection course for waterproofing membranes. The desired sheet lengths are cut to size and retained at the top of the waterproofing membrane by PERMINATOR TAPE or TERMINATION BAR. PERMINATOR 10 mil is also ideal for use over horizontal applications of MEL-ROL LM.

MEL-DRAIN™ drainage board is designed to remove moisture from around footings and relieve hydrostatic head pressures. Eight versions are available.

TERMINATION BAR is provided in 10′ (3 m) lengths for your attachment needs.

MEL-DEK™ waterproofing system provides an excellent waterproofing membrane for bridges, parking decks or other vehicular traffic structures to be overlaid with an asphaltic concrete wearing course. Ideal for repair, maintenance or new construction applications.

Those are a lot of products! But each has its own specific purpose and use. Contact us for professional advice on which of our waterproofing products will be most suitable for your project.

Product: Sealmastic – Emulsion-type waterproofing

SEALMASTIC emulsion-type dampproofing is a breather-type which permits moisture vapor to escape through the film, while remaining resistant to water penetration. This prevents blistering of applied films. The product can be applied to green concrete (not totally dry).

SEALMASTIC emulsion-type dampproofing coatings are ideal for reducing dampness and moisture infiltration through foundation walls, parapets, firewalls, tanks, culverts, cisterns, and bridge abutments. They are also applicable for stone-backing, above-grade cavity wall applications and below-grade masonry wall dampproofing. The SEALMASTIC product line also helps to minimize internal structural damage from mildew and mold, and is compatible with ICF foam forms.
