How to Use Sika Post Mix


Sika Post Mix is a popular product that homeowners use to fill in gaps and voids where concrete or cinder blocks are not present. It is made from small gravel, sand, portland cement and water. The main advantage of this type of mix as opposed to other types of construction materials is the versatility it offers for many different applications. Sika post mix can be used as an underlayment for asphalt shingles before they are installed on a roof, mixed with soil to create level ground for landscaping purposes or even used as a base material for residential driveways. For those who have never tried using sika post mix before, we will give you some tips on how best to go about using this versatile material!

The sequence of these steps will depend on your design, but the most common is to dig a hole for each post and pour in enough sika mix until it reaches ground level. You don’t want any voids or divots where posts should be standing without support under them so use a spirit level to make sure it is straight. Then pour the mix into this area, making sure not to fill in any overhanging areas such as posts or steps and allow for expansion of up to 0.25 inches per linear foot (i.e., for every 12-inch length) after installation, but no more than 15%. For best results, you want at least even distribution so that each post stands on its own without being too wobbly.

To start, you want to make sure that the area where you are going to use sika post mix is level. This will help avoid any possible complications with installing it in an uneven surface. To do this take a taut string and stretch it across two nails hammered into the ground at either end of the area (or as close as best). You then measure out from each nail on one side (the same distance) marking these points on your string with chalk or spray paint if needed. Then simply shift over and mark off another line between them for symmetry’s sake before removing all pieces of debris or loose material from underfoot. If you have concerns about how level the space may be, feel free to employ some leveling equipment such as a spirit level to make sure it is straight.

Then pour the mix into this area, making sure not to fill in any overhanging areas such as posts or steps and allow for expansion of up to 0.25 inches per linear foot (i.e., for every 12-inch length) after installation, but no more than 15%. For best results you want an at least even distribution so that each post stands on its own without being too close together or leaving voids where they should be standing by themselves. The last important step before pouring is trimming off the top edge of your sika post mix with either a table saw blade or hand plane as needed – do not use a miter box because these types of edges are usually too thick.

The hole should be no wider than the footprint of your post and deep enough to accommodate the height of it plus a foot or two so that dirt piles up on top rather than pushes out from underneath. Fill in with soil, compacting as you go along. You can also add gravel for drainage if necessary. Then place posts into this area and fill any remaining voids with more sika mix until they are at ground level too then tamp down again before filling in surrounding areas with loose earth excavated during installation which will help keep everything stable and discourage insects by drying them out quicker without inviting other weeds or bugs to take their place (as long as there is good sunlight).

You want to avoid ever having holes or gaps in the ground that may fill with water and cause potential problems.
