A construction block system comprising:
- A) a plurality of primary blocks each having first and second longitudinal walls with upper and lower surfaces and kept at parallel and spaced apart relationship with respect to each other and further including first, second and third transversal walls each having upper and lower surfaces and extending perpendicularly to said first and second longitudinal walls to define first and second cavities, and each of said first and second longitudinal walls including first and second rectangular walls, respectively, extending outwardly and having smaller dimensions than said first and second longitudinal walls thereby defining first, second, third and fourth peripheral edge walls perpendicular to said first and second longitudinal walls and each of said first, second and third transversal walls upper and lower surfaces further including each a pair of aligned channels and said primary blocks abuttingly coacting with each other to form a structure;
- B) a plurality of primary half blocks each having third and fourth longitudinal walls kept at a parallel and spaced apart relationship with respect to each other and fourth and fifth transversal walls extending perpendicularly to said third and fourth longitudinal walls defining a third cavity and each of said third and fourth longitudinal walls including third and fourth rectangular walls, respectively, extending outwardly and having smaller dimensions than said third and fourth longitudinal walls thereby defining fifth, sixth, seventh and eighth peripheral edge walls perpendicular to said third and fourth longitudinal walls, each of said fourth and fifth transversal walls having upper and lower surfaces that include a pair of aligned channels each and said primary half blocks coacting with said primary blocks to complement said structure;
- C) at least one base alignment and leveling tool that includes two rails mounted on a plurality of transversal members walls and said rails kept at a parallel and spaced apart relationship with respect to each other, said rails being cooperatively received by said channels of said transversal walls lower surfaces resting on a supporting substantially horizontal surface, said transversal members include a centrally located through hole for cooperatively receiving a location fastening member that passes through penetrating and engaging said supporting surface and said transversal members thereby securing said base alignment and leveling tool at a predetermined location, said transversal members further including at least two threaded openings and corresponding leveling bolts that are matingly passed therethrough to coact with the supporting surface to level said base alignment and leveling tool and the abutting primary and primary half blocks.
