KERDI Shower System

systemWith the abundance of ceramic, porcelain and stone tile used in bathrooms and kitchens, you might think it is the ultimate waterproof building material. Well it’s not. Moisture can be absorbed in grout lines and get behind the tile or into the backer or framing and lead to mold, rot and tile failure.

The Legacy Building Company relies on Schluter Systems KERDI waterproofing products for our tile installations. It is a complete, integrated family of components that ensure watertight surfaces and joints. It also makes it efficient for us to fit any size space and achieve flat surfaces, square corners and straight edges when we tile.

The Schluter KERDI system provides a variety of preformed shower components for niches and benches. This speeds surface preparation and ensures reliable, uniform results. To be positive our custom KERDI shower bases will be leak free, we fill the pan with water for 24 hours before we install the tile.

The KERDI system includes waterproof board with a foam core and polyethylene surface. We waterproof our custom drypack mortar shower bases with KERDI membrane. Joints and plumbing protrusions are finished with KERDI Band and KERDI Seal collars. Everything is installed with appropriate thinset mortar.


Distinctive Penny Floor

The Legacy Building Company enjoys designing and building remodeling features that are unique, memorable and add value to our clients’ homes. This penny floor is a great example. We installed the floor in a guest bedroom and home office in a Minnetonka and have the chiropractor bills to prove it!

The Star Tribune featured the penny floor on the front of its Sunday Homes section on Nov. 20, 2016. Read Kim Palmer’s article here

The floors incoporate 258 pennies per square foot (nearly 100,000 pennies total) that are glued in perfectly straight rows for even spacing and covered with self-leveling, two-part epoxy. The base is brown epoxy-painted self-leveling concrete over low voltage heating cable and hardboard that’s stapled 6-in. oc on the edges, 8-in. oc in the field with panel joints staggered 2-feet. Expanding foam was used around the perimeter to contain the epoxy while it set.

First, we separated pennies into two buckets, one for shiny new pennies and the other for darker old pennies that had oxidized. That made it easier to create a random field of light and dark coins as we adhered each coin with a dab of construction adhesive. All of the pennies in the office are oriented tails up. The bedroom floor is all heads. (We resisted the temptation to reverse one coin in each room).

The biggest challenge was to achieve a flush transition between the new penny floor and the hardwood flooring in the hall between the two rooms. The combination of the epoxy, pennies, paint, cement and hardboard over the plank subfloor worked out perfectly. If the hallway floor had been higher, we could have used thicker underlayment.

Why hide money under your mattress when you can enjoy it – and see it – every day. Some 75 percent of all transactions are electronic, and it costs 1.7 cents to make a penny (which is 97.5 percent zinc and only 2.5 percent copper). That’s why the US Mint has been lobbying to discontinue the penny. It’s a matter of time. When that happens Legacy penny floors will be truly priceless!

If you would like to see a penny floor, check out the floor at the Butcher & Boar restaurant in Minneapolis. That’s what inspired us to invest in the novel flooring technique.


Helical Piers and Cantilevered Beams

When an old porch/deck addition on a steep slope settled, several contractors suggested the Eden Prairie homeowner demolish the structure and rebuild. The Legacy Building Co. took on the challenge and saved the structure.  After consulting his soil engineer and structural engineer, Craig  suggested lifting the porches on a pair of massive Parallam beams with stacked-timber cribbing and hydraulic jacks.  By cantilevering the beams, Legacy  was able to install deep, screw-like helical piers without disturbing the failed footings or soil. The corner piers are further stabilized with helical tiebacks driven diagonally into the bank. Legacy also saved the large deck by using a stand-behind Bobcat that just fit under the structure to install the helical piers. As a result, the project cost several thousand dollars below the initial estimate.  See the Ultimate Powerlift blog for photos. The dropped beams will be concealed by a new lower deck.
