Margie E. Shedriek appeals from the order of the Court of Common Pleas of Delaware County which denied her post-trial motions filed after the court directed a verdict in favor of the William Penn School Dis-*164tricf/Penn Wood High School. Shedrick filed a civil action against Appellee claiming damages for injuries suffered when she slipped and fell on a wet terrazzo floor in Appellee’s high school. Jury trial was held February 1, 1993 on liability only on Shedrick’s claim against the School District. The trial court directed verdict for Appellee after the close of Shedrick’s case, concluding that her evidence was insufficient on the issue of the defective condition of the floor and She-drick’s claim therefore does not fall within the real property exception to governmental immunity.1
This Court’s scope of review of the trial court’s grant of directed verdict is limited to determining whether the court abused its discretion or committed an error of law which controlled the outcome of the case. Mitchell v. City of Philadelphia, 141 Pa.Commonwealth Ct. 695, 596 A.2d 1205 (1991). In deciding a motion for directed verdict, the trial court must accept as true all facts and inferences which support contentions made by the party against whom the motion is made and shall reject all testimony and references to the contrary. Morosetti v. Louisiana Land & Exploration Co., 522 Pa. 492, 564 A.2d 151 (1989), citing Jozsa v. Hottenstein, 364 Pa.Superior Ct. 469, 528 A.2d 606 (1987), appeal denied, 518 Pa. 619, 541 A.2d 746 (1988).
In her appeal to this Court, Shedrick claims that the trial court erred in granting directed verdict in favor of Appellee because she established that insufficient matting protection of the building floors falls within the real property exception to local agency immunity. Moreover, Shedrick maintains that her testimony along with the testimony of her expert witness provided sufficient evidence to establish an artificial condition of and a defect in the School District’s property itself; the floor contained water not sufficiently protected by mats which establishes the artificial condition and the floor did not contain an abrasive protection which proves the defect.
Shedrick’s claim arises out of an injury sustained on September 20, 1989 when she entered the high school where rainwater had caused the terrazzo floors of the school building to become wet and slippery. Heavy rains had occurred throughout the day and persons entering the school building tracked rainwater onto the floors. Shedrick slipped on a portion of the building's floor not covered by mats although the building custodian had mopped and laid mats in an effort to keep the floors in a dry condition.
The Pennsylvania Supreme Court has specifically held that the real property exception to governmental immunity applies only to eases where the artificial condition or defect is “of’ the land itself, as opposed to a condition or defect which merely facilitates injury to the plaintiff. Mascaro v. Youth Study Center, 514 Pa. 351, 523 A.2d 1118 (1987); 42 Pa.C.S. § 8542(b)(3).2 The Supreme Court recently decided Kiley v. City of Philadelphia, 537 Pa. 502, 645 A.2d 184 (1994), where the Court reiterated earlier holdings and made abundantly clear that the real estate exception to the rule of immunity applies only in cases where it is alleged that the dangerous condition of the land itself causes injury and not where the dangerous *165condition merely facilitates injury by the acts of others.
Immediately prior to Kiley, this Court decided Finn v. City of Philadelphia, 165 Pa.Commonwealth Ct. 255, 645 A.2d 320 (1994), which overruled Shubert v. Southeastern Pennsylvania Transp. Auth., 155 Pa.Commonwealth Ct. 129, 625 A.2d 102 (1993), and held that in cases involving the real property exception to immunity, liability can be imposed on the government entity only where the plaintiffs injury is caused by a defect of the real estate itself. Hereafter, liability will not be imposed for injuries caused by the negligent failure of a government entity to remove foreign substances from real estate. The Court emphasized however that liability may be imposed where the defective design, construction or condition of the real estate itself results in an unnatural accumulation of a substance which creates a hazardous condition causing injury to the plaintiff.
The trial court accurately analyzed the law and concluded that Shedrick’s attempt to establish negligence through testimony of the degree to which the floor was slippery at the time of the accident was insufficient to meet her burden of proof, and the alleged insufficient matting of the floor does not bring this claim under the real property exception to immunity. The rainwater on the floor of the high school neither derived nor originated from the School District’s real property, and no evidence was offered to establish that the floor itself was defective. Moreover, the trial court found that nothing was offered to either prove or infer that a terrazzo floor is inherently dangerous or slippery. Shedriek’s expert witness, who examined the building’s floor more than three years after the incident, offered no opinion or knowledge relative to the application of an abrasive on the floor at the time of Shedrick’s fall nor competent evidence to demonstrate how the floor became hazardous when wet.
The Supreme Court has cautioned that the real property exception must be strictly construed. Snyder v. Harmon, 522 Pa. 424, 562 A.2d 307 (1989); Mascaro. Hence, the critical question concerns whether the alleged artificial condition (rainwater) or the defect (lack of abrasives) is of the real property itself. On this question, the trial court accepted as true all facts and inferences tending to support Shedrick’s contentions and appropriately ruled against her in determining that the evidence failed to demonstrate an artificial condition or defect of the floor itself which would bring this case within the real property exception. Thus Shedrick may not recover under the real property exception to immunity based upon precedent and this Court’s recent holding in Finn and the Supreme Court’s holding in Kiley. Finding no error by the trial court, this Court has no alternative but to affirm the order denying Shedrick’s post-trial motions.
