          Polyurea is a liquid or spray coating that is used successfully for waterproofing parking garages, flooring, reservoir/tank linings, flat roofs and basements. Polyurea coatings are impact resistant, flexible, durable and are often used to repair concrete or steel surfaces. These coatings have been in use for 30 years and some formulas will dry within 4 to 6 hours. However, proper surface cleaning and preparation must take place - any sharp edges left in the surface to be coated will break the membrane. The reason some waterproofing membranes fail is because of improper surface preparation - the surface's sharp protuberances have not been taken care of nor was the cleaning sufficient. Skyward Waterproofing Technicians have been trained and tested in different environmental applications before they are allowed to preform waterproofing for residential or commercial clients. 

Inspection of Basements or Cellars, for needed Polyurea waterproof treatment, would look for some typical signs of water infiltration through basements or cellar walls. Such as: musty smell, cracks in the walls, basement floor cracks that exhibit heaving, water seeping in from the seam where the wall meets the floor and the bottom row of concrete blocks could be damp with a white powder on them. This white powder is called efflorescence an alkaline substance composed of salts and minerals that will leach from concrete exposed to near constant moisture.  These damp basements also encourage the nearby rodent and insects to take up residence in its warm, dark and damp space. Polyurea waterproofing will remove these positive living conditions for roaches and mice by closing all cracks or holes that let these critters in with ground water.

Polyurea Waterproofing in New York City

• We work with homeowners, home restoration builders, co-op and condo associations and commercial property owners to offer waterproofing services for Homes, Brownstones, Apartment buildings, commercial buildings and Lofts in New York City and surrounding communities. All specifications are followed to the standards required for each application by the industry and government regulations. Providing protection against the most destructive force in nature will keep the building structure strong with a healthy atmosphere (dry environments discourage molds and pests).
• Polyurea is a liquid or spray coating and is used successfully for waterproofing flat roofs, basements, parking garages, flooring and reservoirs/tanks linings (even tanks holding drinking water). A Polyurea application forms a seamless monolithic flexible waterproof coating over building materials which are degraded by water seepage, damaging UV rays, heavy rains, and other weathering.
• We have had three decades to study the incredible waterproofing performance and the best formulations of these waterproofing coatings. These coatings are often used routinely in wet environments to repair concrete or steel surfaces. Some formulas will dry within 4 to 6 hours - a big advantage when you need a structure protected and back in service. 
  

How leaks happen through the most common basement materials:

• Basement walls will leak along the floor and wall joints as they are an access point with a weakness (a seam). However, water will even leach through the walls themselves if enough water pressure exists outside.
• Concrete block walls will commonly leak along the floor/wall joint and between the mortar joints between the concrete blocks if the outside water pressure is high enough. Also, the hollow cores in concrete block can fill with water which will cause leaking for some time after all has dried up outside. Water is a very formidable force of nature and hard to hold back when there are cracks to flow into and beyond.
  
• Poured concrete walls will leak along the floor/wall joint because the cold joint is the weakest point. Even seepage through the walls can occur as the water pressure from outside the foundation builds up (why gutters and downspouts are important). 
  
• Clay tile walls found on historic dwellings will mostly leak at the floor/wall joint and the joints between clay tiles are also common places to leak. Clay tiles also have hollow cores that can form a reservoir of water to continually leak into the basement. This non-rainy-day leakage often confuses clients.

Basement Waterproofing

• Polyurea Waterproofing for basements and foundations: Many neighborhoods, like Yonkers in New York City, have very little wiggle room to spread out to build storage sheds in yards to store necessary yard tools, Christmas supplies, home repair tools… so we look to our basements for such storage. However, wet basements will cause rust to eat away at tools, mold to settle on treasured decorations and will only get worse the more we pack things into the area. To keep our storage items safe from decay in our homes basements, we need to control water intrusion. Skyward Roofing has an affordable solution to dry out these basements and clean up the air quality in the rest of the home using methods designed specifically for each homeowners’ unique situation.
  
• Waterproofing your basement will enable storage of treasures, books, photographs and extra linen without that ever-present smell of mildew. Most of a home’s atmosphere has a lot to do with what floats up from the basement so if respiratory infections seem never-ending, request us to come and perform a free waterproofing estimate of your basement or cellar space.
  
• Additives can also be added to make a floor coating slip resistant - a good safety improvement for a basement floor. The spray application ensures that the proportions in the compound are accurately mixed so the quality will be uniform throughout the target surface.
  
• Estimates for Polyurea Waterproofing can be prepared within a day in most cases, but sometimes in complex environments it may take a few days. We always make sure to factor in all the necessary steps to bring you the result of a waterproof basement or roof. A detailed written report will be submitted for you to review. The estimate will explain what has to be done to provide a long-lasting waterproofing to correct all paths of moisture infiltration in a budget-friendly way. We will not advise costly solutions when less costly ones are suitable.
