Job Stories From Twin Falls County, ID
David's Dream Deck in Boise!

David from Boise spent all spring building his dream deck. David's brother in-law told him to dig a 3ft deep hole and fill it with concrete as the footing to support the structure above.  Because his brother in-law is a contractor, David took his advice. By the end of spring David had his dream patio finish just in time for the summer.

Summer storms left 6 inches of water in David's back yard turning it in to a swamp. When the water was gone David walked around inspecting the damage.  As he stood back away from the patio, he noticed it was lower on one end. He could see that the water had moved the soil down lower and now his newly built deck was less than perfect. He knew he could fix this issue but that it could turn into a reoccurring issue over the years and David was just ready to enjoy his deck.

David jumped on the web and searched in Boise, Meridian, Eagle, Mountain Home, Twin Falls, Nampa, Caldwell, Kuna, Garden City, Ontario and Pocatello. He was looking for a long-term stabilization product for his deck. He knew that with a long-term stabilization product he wouldn’t have to worry about this issue for a very long time.

That’s when David gave us a call!   

We sent one of our foundation specialists out to look at the deck. Our EZ Post Helical Support System was exactly the product David was looking for! In addition to offering the utmost strength and stability, EZ Post offers many other benefits over traditional concrete footing. Installation can be completed year round. EZ Posts are also installed deeper than traditional concrete footings, making them less susceptible to changing moisture content in the soil. But what David loved the most was the 5 year warranty.

Now David can sit back and enjoy his deck year after year with no issues.

Structural Repair, WaterGuard sub-floor Drainage System

Homeowners had a vertical crack in the concrete wall of the basement, visible from the interior and exterior.  Water intrusion occurred during heavy rain fall and snow or ice melt.  For the structural repair we used FlexiSpan crack repair system to both seal the crack and provide a secondary method of protection in case of a small leak.  The WaterGuard sub-floor drainage system with SuperSump pump system and discharge line has been custom designed and installed for the space.  To protect the hom from mold growth and prevent humidity from evaporating into the basement, the SuperSump system features an airtight lid, drain and a CleanSpace liner.

This customer reached out to us because she needed her crawl space treat for health reasons. Once they called, we rushed right out to their home to see what we could do to help. The following week we installed out Cleanspace product in their entire crawl space. We use Cleanspace when we are encapsulating/conditioning a crawlspace. Once installed the home becomes safe from unwanted toxicins that come up from the goound underneath of the home. This is just one of the many benefits of getting your crawl space encapsulated with our Cleanspace product.Twin
