How to install READYWALL
Note: This guide should be used with site preparation methods stipulated by Wallmaster. Walls should be arranged to be delivered within 1 day of the planned starting day of your installation as if stored incorrectly they can warp and create extra work during the installation.
Now the walls are at home, how do I install them?
First the site should be prepared by ensuring the bottom height where the wall will sit has been dug at or slighty below the bottom height of the lowest sleeper wale (cross rail), this is required for all types of retaining wall.
Now the site is prepared using a string line mark the hole locations (tip: use Spray Marking paint), then holes should be dug to 100mm longer than the post leg to allow gravel to be placed at the bottom of the hole for drainage. Holes must allow 100mm of concrete to surround the post as a minimum. (tip use a post hole digger to dig the
holes with a 450mm auger – either you operate or a machine and operator). For box panels there are no holes required
Run a string line along the length of the wall just above what the finish height will in line with the inside or outside edge of the cap on each straight side of wall or box to ensure straightness and height is correct. (it is easy to measure the distance from the string line to the top of the wall as you are standing the wall and this also ensures the wall does not alter the line of the string as it wont be touching it.
Stand the starting section first in its holes (or position for boxes) and support it at the correct height (tip: checking this against the string line), when supported at the correct height place the stainless steel biscuit into the slot route so the next standard/running length capping slot route can be slid over it. Stand the running length of wall in the holes with the non posted end closest to the previously stood section and slide this running length into the previous section so the cap is butted up tightly (you will have noticed the cap sits on top of the previous post), now fasten the top fastener only when it is at the correct height and closed at the join.
Adjust the height on the other end (posted end) when your height is correct, support (tip: if you use a straight edge sat across the join and it touches the cap along it’s entire length should be straight).
This process should be repeated when joining all sections together, Readywall can be adjusted slightly after initial installation if required prior to concreting or setting a box by filling with dirt, you may need to prop/brace the wall at the correct angle.
When you have completed standing the wall in the correct position and you are happy with how the wall is situated now put in the remainder of the fasteners. You should now concrete the wall into position using 20 Mpa concrete or stronger (tip don’t use rapid set concrete as this is not of a structural grade, normal concrete is also cheaper). Boxes should now be filled with appropriate filling.
Socked Agricultural slotted pipe (ag pipe) should be placed behind the wall, it is also recommended that you allow for the ag pipe to have a flush point so if it becomes blocked over time it can easily be cleaned out. Backfill with a suitable free draining backfill, when the concrete surrounding the post has set fully.
Potential problems that can occur are a wall is slightly twisted this is rectified by simply propping bracing back the way required (sometimes the post bottom will need to be braced as well to stop the wall from pushing away from the desired line).
CORNERS
Note: Corners caps join any two wall sections over posts at the designated angle of the corner capping piece corner caps can be ordered in any angle.
Connect corner capping insert into first wall section by placing the stainless steel biscuit into the wall section cap, then slide the corner capping insert into position ensuring a flush joint with the wall capping, then screw this into place through the cap then wall section post. Now slide the next wall into position after first inserting the stainless steel biscuit, when the wall capping is sitting flush at the front with the corner piece and the joins are butted up tight, you may now screw into the final position through the post. You have now finished the corner and can continue joining running sections onto these walls if required.
Post fillets are available to dress up post joins and are highly recommended.
