Annular Space Grouting. As the nation's pipeline infrastructure continues to age, more emphasis must be placed on repairing these underground systems. Sliplining and relining are two solutions that allow the installation of new pipe without having to dig a new trench. The existing pipe becomes âthe hostâ for a new carrier pipe which is slipped into place. The annular space between the two pipes is then grouted to protect against shock and corrosion. The result is a âgood as newâ pipeline installed at substantial savings compared to traditional installation methods.

Lawn aeration costs depend on the size of the lawn. Most averages show lawn aerating to come in at about $175 for the procedure, and owners can spend anywhere from $.10 to $.35 per square foot. If aeration is being done by the homeowner, they can expect to pay rental fees of $65 to $250 per day. Machines can be rented at home improvement stores. In general, most aeration methods are based on either a manual or a motorized aerator. For smaller lawns, a manual aerator works best.
