  • Cement structure containing a waterproofing layer
    Patent number: 6489032
    Abstract: A process of providing a waterproof concrete structure comprising the steps of (a) providing a layer of a concrete composition on a support; (b) spraying on to this concrete composition a waterproofing layer; and (c) applying to the waterproofing layer a further layer of a concrete composition; characterized in that the waterproofing layer is provided by a composition which comprises an aqueous dispersion of coalescable particles of thermoplastic polymer. The method is useful in the waterproofing of tunnel linings.

  • Hardenable acrylic monomer compositions
    Patent number: 5712337
    Abstract: A hardenable composition suitable for flooring and for coating concrete surfaces comprising(a) an acrylic binder comprising a (meth)acrylic ester of the formula ##STR1## where R.sub.1 is C.sub.2-6 alkylene, n is 0-3 and R.sub.2 is a radical of an aromatic or alicyclic dicarboxylic acid ester or a dicyclopentenyl radical, n being 0 only when R.sub.2 is a dicyclopentenyl radical, and(b) a component which is one or both (preferably both) of carbon black and a polyfunctional aliphatic or aromatic polyester- or polyether- urethane oligomer. The composition also preferably comprises aggregate such as sand. The compositions have excellent impact resistance and flexural strength.
