One of the readily available material due to its numerous advantages is polyethylene terephthalate (PET) which is commonly used for containing carbonated beverage and water bottles among others. Hence, this project access the possibility of PET bottles filled with lateritic sand for a composite wall construction system. Collected laterite was air-dried for seven days, sieved with 4.75mm BS sieve size and bagged, 90 specimen cubes were produced with clay soil samples replacing the conventional fine aggregate, sand; embedded with laterite filled PET bottles arranged horizontally, the mixes were prepared by proportioning for 10% and 15% cement stabilization and representative cubes air-dried for respective curing period . Specimens of both empty PET bottles and laterite filled PET bottles were tested at 3, 7 and 14 days for compressive strength and for 14 and 28 days for flexural strength. . Results showed that test specimen for control and stabilized specimen with 15% cement stabilization had the highest 14 days average test result in compressive strength. However, laterite filled PET bottle failed to improve flexural strength of cubes. Based on the research, it was recommended that poured clay containing 15% cement stabilization could be used for construction of
