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.
Contact retaining wall suppliers for materials quotes. Based on regional NSW council estimates, the cost* of having a one metre high treated pine or block retaining wall built is about $270 per linear metre versus about $440 per metre for a brick retaining wall.
