What is the best rock to use for drainage?

What is the best rock to use for drainage?

The stone should be no less than ¾” and dense (we suggest Granite, or River Gravel) so it will allow good water flow. Lime Rock, although inexpensive, is a poor choice for a French Drain because it will begin to deteriorate over time and eventually begin to pack down and restrict flow.

How much sand do you put under concrete?

Because concrete slabs “float” on the soil, soft ground or voids underneath may cause unsupported areas to crack under heavy weight like vehicles. Pack about 4 in. of sand or gravel over clay and other poorly draining soils to provide even support.

Do I need rebar in a small concrete pad?

You do not need rebar for any slab if you make it thick enough and space the joints properly. Rebar in jointed pavement is there to counter the cupping effect of thermal expansion. I always recommend the use of rebar or at least rewire. Any concrete slab can crack.

Is fiber mesh better than wire mesh?

In addition to providing a more thorough protection for your concrete pour, fiber mesh typically takes less time than wire mesh to use. This is because the wire mesh has to be carefully measured to fit the site of the pour and needs to hold up at a certain level during the process of pouring.

What does adding fiber to concrete do?

Concrete fibers offer an array of benefits, including an increase in strength and the ability to minimize cracking.

Does fiber mesh make concrete stronger?

The purpose of fiber mesh is to reduce water loss from the concrete as well as enhance its structural integrity. This type is also used to create a higher impact resistance in the concrete, prevent thawing, and increase its strength.
