An apparatus and method is provided for structurally renewing and sealing a wall of a manhole. The apparatus includes a tubular sleeve impregnated with a hydrophilic or hydrophobic material capable of expanding when in contact with water, and a liner impregnated with a resinous material capable of curing and hardening. The apparatus is positioned in a manhole and inflated, which forces the tubular sleeve and the liner into contact with the wall of the manhole. The hydrophilic or hydrophobic material is forced into defects of the wall, thus sealing the wall, while the liner is allowed to cure and harden, thus structurally renewing the wall of the manhole.
