OAKCREST GIRLS SCHOOL – VIENNA, VIRGINIA
OAKCREST’S PERMANENT HOME – New Building Opened Fall 2017
1619 CROWELL ROAD | VIENNA, VIRGINIA 22182
As with traditional construction procedure, Omni Block was required to prepare a mock-up of the materials and finishes that would ultimately make up the final building appearance for final owner and architectural approval.
The grey block above will be covered with the stone veneer that is depicted in the photo to the left. The white block is an upgrade and was fabricated with an integral water repellent additive since it will be left exposed as the actual finish.
The photo above shows the Omni Block System 12 (12″ thick). This block has 4 layers of masonry and 3 layers of Expanded Polystyrene (EPS) insulation equalling an R-26. The cell voids are where future vertical rebar will be placed and then solid grouted for structural strength.
The school’s exterior walls are a combination of System 12 and System 8 block. The areas that will be covered with a decorative stone veneer are of the standard grey variety and are 8″ thick block. The System 8 is an R-19.6.
Anytime block is going to be exposed and used as the architectural finish, a flashing to allow potential moisture buildup to escape is recommended. BlockFlash from MortarNet was used in this building.
