Details

Failures most often occur when rough openings and penetrations are not detailed correctly.  If left unaddressed, they can provide a pathway for water ingress.  Prosoco's comprehensive detail guide can help you make sure that your building envelope is tight and that water stays where it should: outside of your walls.

Material Selection Chart

This chart from Prosoco helps clarify which of their products can help you achieve your project's design intent.  Most of Prosoco's air barrier materials are certified to have no "Red List" chemicals in them, leading their R-Guard systems to be used on some of the greenest buildings in the world (and locally).  

Rain Screens

Continuous Insulation

ASHRAE 90.1 is an international standard that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings.  This standard defines continuous insulation as: "insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings."

Masonry Cleaning & Restoration

Know Your Substrate

With so many varieties of stones and brick used in construction today, it can be a difficult task to identify the substrate you are looking to clean.  Concrete, marble and limestone (calcium-based materials) will react differently to cleaning agents than granite, brick or sandstone (silica-based materials).  First step, identify your substrate!

Waterproofing Materials

This article from the Concrete Network describes different types of materials for foundation waterproofing.  This includes sodium bentonite, the active ingredient in many of CETCO's products.  Sodium Bentonite is safe to work with, non-polluting, easy and quick to apply, and can go on even at low temperatures.

Sodium Bentonite

High swelling sodium bentonites make superior waterproofing products, which is why CETCO has used these organic clays in their waterproofing materials for decades.  CETCO has even branched into creating advanced polymers that mimic and enhance the swelling seen in bentonite material.  The article below gets in-depth to the chemical structure of sodium bentonite.
