The Cistern Concrete Walls

Construction of concrete walls is a crucial phase in building construction.

The cistern concrete walls.

The four walls of the cistern are stone foundation walls presumably as thick and strong as the rest of the house s stone foundation walls. You should lay concrete into the sides of the trench after the base has completely cured in order to set the terra cotta tile for your underground cistern. Allow the cement to dry for 24 hours before filling the cistern with water. A typical arrangement for a roof catchment cistern system is shown in figure 1.

Use a caulk gun filled with a slightly watered down cement mixture to pump cement into any cracks in the cistern walls. The cistern typically located underground may be constructed of various materials including cinderblock reinforced concrete or precast concrete fiberglass or steel. The cistern itself was designed into the concrete structure of the house and includes rubber dam gaskets at the base and ceiling of the tank at the junction of the separate concrete pours. Concrete tanks can be made to support traffic loads i e can be put under driveways or parking lots improved water quality.

The cistern has eight inch reinforced concrete walls with another partial wall in the center to divide the tank into two halves. Very common throughout brazil for example they were traditionally made of concrete walls much like the houses themselves with a similar concrete top about 5 cm 2 inches thick with a piece that can be removed for water filling and then reinserted to keep out debris and insects. This will seal the cracks and help prevent the cracks from spreading. Modern cisterns are manufactured of plastic in brazil with a characteristic bright blue color round in capacities of about 10 000 and 50 000 liters 2641 and 13 208 gallons.

Moreover concrete wall is a desirable structural element in earthquake prone areas since it exhibit hellip. It is constructed as a load bearing structure to transfers loads from floor to the wall below or to the foundation in addition to divide spaces in multi storey buildings. Cisterns are normally covered and dark with no natural light available during application. Concrete systems are usually the least expensive option.

If your cistern was previously coated with a white finish consider applying gray damtite powder waterproofer as first coat to insure you do not miss recoating any areas. Designed to achieve the us green building council s leadership in energy and environmental design leed platinum rating the center features a 950 000 liter 250 000 gallon underground concrete cistern. The largest of its kind in the continental united states this tank will capture rainwater to irrigate the center s gardens and forests. Damtite powder waterproofers perform equally well in both white and gray colors.

The cistern supplies water to the household through a standard pressurized plumbing system. Concrete walls tend to neutralize rainwater s acidity for a more balanced ph inexpensive. The cistern walls are parged with some kind of mortar that has some damaged spots but is surprisingly tight and solid.
