Aetnaâs standard HMO plans cover surgical dressings when they are medically necessary for wound debridement or for the treatment of a wound caused by, or treated by, a surgical procedure. Please check benefit plan descriptions.
The only drawback to this type of retaining wall is the lack of lateral strength it has. If too much water or extra pressure is exerted on the wall, it could fail in spots. Expect to pay between $15 and $30 per square foot of wall, depending on the style and strength of block you choose.
Simply enter the dimensions for your wall project and the concrete block calculator will figure out how many blocks are needed. For example, a 10â² x 10â² wall using a 16â³ x 8â³ x 8â³ block will require an estimated 120 blocks and cost about $185 for material.
