![]() ![]() In most areas the large retaining wall blocks are simply plain with a standard concrete finish, but in a few areas the blocks are offered with a brick or slate finish for a more ascetically appealing wall finish. ![]() If you have a lot of moisture or a taller wall you may also need to install drainage pipe. A layer of rock or gravel 8¨ – 12¨ works well. Another thing to possibly consider is drainage. This is up to you as Concrete Block Supply provides blocks and not engineered walls. Depending on your specific application and how high you are making your retaining wall you may want to put a mesh fabric in between your block row to offer your wall more resistance against the soil. Most people only going a few blocks high and choose not to use any type of geofabric because the weight of the large retaining wall blocks is enough to hold back the soil. This type of retaining wall type is called a gravity wall because they use their own weight to hold the soil behind them. The first step is to measure out how long of an area by how high of an area you need to form your wall. Most flatbed trucks can ship 13 (6’x 2’x 2’blocks) or 9 (5’x 2.5’x 2.5’ blocks) at a time so any multiple of 13 or 9 will get you the best bang for your buck if you want the blocks delivered. You will begin by leveling out the area for your first row of blocks. Set your first row, making sure each block is firmly set and level. Once you set your first row the second row and beyond will go much faster. It is recommended that you offset the blocks so that the joints do not line up, this will offer you more strength at the joint. At 6´L x 2’W x 2’H and 3500lbs or 5’L x 2.5’W x 2.5’H and 4,700lbs they make quick work of building a retaining wall. A very popular use of precast concrete retaining wall blocks is to use them to form a cost effective retaining wall. ![]()
