TERRALITE® TOP TWENTY
The top 20 questions asked about the Terralite® Retaining Wall System
1.Do I need mortar?
A)No. Each Terralite® unit is designed to stack and interlock without mortar.
2.Do I need a concrete footing?
A) No. Terralite® should be placed on a firm, flat surface and approximately one inch of block should be below grade for every foot of wall elevation.
3.How does it lock together?
A)The unique curved shape of the block that allows it to rotate also gives it the interlocking strength. By using the full surface area of the interconnected curves, the block has the same type of connection as the ball and socket used in nature. Also, by filling each block with crushed rock, the rock aids in locking as well as adds weight to the unit, making it a mass gravity system.
4.How high can I build a Terralite® wall?
A) Terralite® is designed for walls of 3 feet or less. For larger walls you can terrace the area by going back toward the bank twice the vertical height of your lower wall, then start a new wall. Alternately you can use an engineered soil retention grid between courses, or use the larger Terraforce® wall system.
5.Can you use Terralite® to make a straight wall?
A)Yes. The same unique shape that allows you to create flowing curves also allows you to make a straight wall.
6.Can I use Terralite® as a retaining wall?
A)Yes. Terralite® is an engineered retaining wall system that keeps it’s inherent strength as the wall curves and flows.
7.Can I use Terralite® to build stairs within my wall?
A)Yes, the same great design that allows you to build flowing and entwining walls allows you to build stairs. See your local dealer for more information
8.Do I need a setback between courses?
A)Terralite® can be stacked vertically up to two feet, or,with a setback of 1 inch per course it can be stacked to 3 feet.
9.Do I need pins or clips between the rows?
A)No. Terralite® does not require any pins or clips that add to your wall cost.
10.Do I need to fill each block?
A)Yes. Every block should be filled as you complete each course of your wall. They should be filled with a clean crushed rock, then the top course may be filled with topsoil if you wish to have plants, or it can be filled with a decorative rock, or capped using the Terralite® cap unit.
11.Do I need to put anything behind the wall?
A)We recommend you have approximately 1 foot of drainage material behind your wall to deal with any water that may build up and a length of drain tile at the bottom to remove the water.
12.Do I need any special tools?
A)Simple hand tools including a shovel, wheelbarrow, level, string line, a brush or broom, and gloves are all that should be required.
13.What are they made from?
A)Each Terralite® block is made from concrete. They are environmentally safe, durable, and won’t leach or rot.
14.How heavy are the blocks?
A)Each Terralite® unit weighs approximately 19 pounds. They are usually palletized in bundles of 150 pieces, for a pallet weight of approximately 3,000 lb..
15.What are the dimensions?
A)Terralite® is 6 inches tall and approximately 7 inches wide. There are 1.71 Terralite® per linear foot, 3.43 Terralite® per square foot, or 36.92 Terralite® per square metre.
16.Is there a cap unit available?
A)There is a cap unit and it comes in all the colours. It is the same shape as the block so it can curve and flow with your wall.
17.What colours of Terralite® are available?
A)Terralite® is currently available in Natural Grey, Tan, and Mojave.
18.How much does it cost?
A)Terralite® is a very economical retaining wall system and the price per unit varies due to colour selected, the quantity needed, and availability in your area. Your local Terralite® retailer will be glad to give you a quote for your project.
19.Where is it available?
A)Terralite® is available throughout Vancouver Island at most building supply outlets.
20.Can I do it myself?
A)Most people can install Terralite® themselves. We often hear from our customers how much they enjoyed building their project themselves, while saving money. If you don’t wish to install it yourself, your local retail outlet can recommend a contractor to do it for you.
