<p>A laminated mat for growing lawns or other vegetation on soil comprises a base sheet of water pervious, bio-degradable web material. Joined to the base sheet by an adhesive binder is a bed of seeds and dried, compressed peat particles. Secured to the bed of seeds and peat particles is an upper laminate comprising a fibrous, porous veil which protects and retains the bed therebelow. The upper veil is water pervious to pass water therethrough to the bed of peat particles and seeds. The bio-degradable veil also easily expands to retain the wet, expanded peat particles and the seeds entrained by the peat particles and the veil.</p> |
